Broken battery problem? Fast drains and incorrect capacity display

I'm worrying about my battery. The main thing is, it drains really fast. In flight mode and nothing else on it drains like 2% each hour. So overnight, most of the time it drains like 16%. Today i started with 100% in the morning. Used GPS for 1 hour, made a phonecall for 20mins in total time. My battery indicator said there was 30% left :/ I know this thing eats batteries, but this is insane. Because i noticed an incorrect display of the battery the last few days i gave it a soft reset. After the reset i saw the battery had only 4% left, not even 30%, but 4! :|
Many times when the phone is saying i have 'insert number' percentage of battery left it's incorrect. Because when i give it a soft reset, it changes the number. Sometimes i get more percentage back, and sometimes it drops.
One hour ago i plugged it on the charger, checked 45min ago, and it was still on 31% battery :| Then, like 10min later i suddenly saw a green light from my phone and it was full.
I've never had a device with a broken battery and i don't know the symptoms, but is this normal or is it likely that my battery is dying?

A little kick!

Battery Charge Issue

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?

Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?

Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.

Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.

same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.

Charging the battery with phone off makes it last longer?

Havent you noticed that when you charge the phone powered off it takes like 40 % more time for the batetry to charge but it also makes the battery last longer? is there any truth in this or im just crazy?

This is a very well know issue related to battery calibration. Take a look at the many calibration threads to learn about bump charging.
Basically, it takes longer with the phone off (or when you pull and put back the battery while charging) because in some cases android was stopping the charge before a full charge.
Try this
Charge your phone to 100% (inside android)
Turn you phone off
Reboot
Pull the battery before it boots
Wait for the ?
Put the battery back in and notice the %
If it says 60%, then you had 40% of your battery not being charge.
If you leave it in that spot and wait for it to go to 100%, your battery will be better calibrated.

and this hasnt been fixed even with gingerbread? yeah i have gotten the message saying it has 60 % :/

I pay no attention to the battery meter anymore. I've found that it just reads low. It's not that it doesn't get a fully charge, the phone can't read the level correctly. I tried draining the battery once by playing an episode of Top Gear with the screen on full brightness. The phone said the battery was at 5% but the video kept playing for another 1.5 hours.

noup , when my batetry says low , it dies pretty quickly

Go with mV.
4200mV=100%
3200mV=0%

Huge problems with my galaxy s3 in the past few days.

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive

if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.

Do a factory data reset on stock recovery. See how that works out first

Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts

[Q] Major battery / charging issue!

Hello XDA Community.
I bought an HTC One off of eBay, and I've been using it for 3 days now (I had a VZW HTC One before but the restrictions from VZW were annoying, let alone the updates that come after 6+ months). I did notice a problem, which is a major issue, since I depend on my phone a lot in my everyday life. The problem is this: The battery seems to lose charge normally at 100% til' 80%, then faster at 80% to 50% and within an hour or maybe less of little to no use, the phone goes to 40-30% percent and then goes from 30% to 20% in seconds, 20% to 15% or 13% in less than 10 seconds, and basically goes from 40% or 30% to 0% in a minute or two (sometimes even 30 seconds or so). It is driving me crazy.
I have been watching the phone, and I noticed something really strange, which made me suspicious of this being a software problem.
I charge the phone and by the time it goes at around 30% (30 or 31 yesterday, 36 today) it just shows the battery without the charging indication (no green filling in the battery, it just shows an empty battery and said percentages). When I unplug and plug back in the phone continues charging, but at a 76 to 80% charge. I would really appreciate some help, and thank you in advance.

Hello my friend. I bought a battery replacement off of eBay and I will go to an expert to change it for me, as soon as possible. I will let you know if the problem is fixed, or if it insists.
